Transmission codes on Framingham Build Sheets for 69 Chevelle

Does the XI car have a posi?

The two build sheets with XI and L78 I have are both posi, KK coded rearends.

I have not seen the car in person, but from what I have seen yes it is a KK rear end and posi.

XC- M20 L48, L35
XG- M20 L35
XF- M21 L78
XI - M22 L78

take care, Andy

My car is a Framingham car with a build sheet, original engine (L78) XD in box 29, bench seat. Clearly a manual from new but I don't know if it could had been a three speed? The shifter is a Hurst not a Muncie, and the gauge carrier is for a manual car. The column is not from a column shift car. The tunnel has torch marks like on a Camaro for a 4 speed, but, I don't know if Chevelles had the same torch marks on the hump like Camaros did or not?
Any other XD codes in box 29 on Framingham build sheets?

Would like to know what all the codes stand for on the build sheet similar to what you can find for Mopar. I only have a partial build sheet for my car. The left side of the sheet that shows up to box 96.

Yes, mine is a Framingham built car. Also, box 29, Axle, is KF for the 355 G80 Posi.
